In my breadboarding I needed a way to bring power to the breadboard. JameCo sells part #101178 which is compatible with the Arduino power adapters but attaching it to a flat surface is a challenge. This support lets you glue the module into the support, and then glue the support to your breadboard. This is designed straight up in Turbocad. If you acquire one or more of the JameCo power jacks then print this part, glue in the power jack, and then you can glue that assembly to your breadboard.
